GIAASSWARE-TRANSFERRIEG DEVICE.

Application filed August 25, 1925. Serial No. 52,344.

This inventionfrelates to take-out devices for removing glassware from fabricating machines, and it has particular relation to devices for removing bottles or other glass articles in an inverted or neck-down posi' tion from the molds of a glass shaping machine, for reverting the articles and fordepositing them at a suitable point of delivery, such as a conveyor or a settingaip buck.

One of the objects of the invention is to minimize shocks and jars to which articles of glassware may be subjected when removed from the molds of a glass shaping; machine in an inverted position, reverted and transferred to a suitable point of delivery within the relatively short interval of time between the arrival of successive molds atthe take-out station. Vite accomplish this object by providing separate mechanisms for performingcertain of these operations, by reducing the rate of movement of the articles during their transfer from the molds to their point of delivery, and also by permitting; the molds to revert, close and move on to the next station as soon as the ware is clear of the molds.

Another object of the invention is to provide a take-out device that will remove bot tles of rectangular, oval or other non-circular cross section from the molds of a shaping machine and will deposit them on a conveyor or setting-up buck with their flat sides, or their major cross sectional dimensions in the case of oval ware, parallel to the edges of the conveyor.

Another object of the invention is to provide a take-out device that is relatively simple in construction and operation, and that is particularly adapted for use in connection with a shaping machine such that described in the copending application for Letters Patent of Edward H. Lorenz, Serial No. 490,567, filed August 8, 1921.

In the accompanying drawings:

Figure l is a side elevational view of a take-out device constructed in accordance with the invention;

2 is a plan view of the structure illustrated in Fig. 1;

Fig. 3 is an ei'ilarged detailed view of the \wire reu'zmdnn mecha. ism

Figs. 9 to 16 inclusive are diagrammatic.

views illustrating the several positions that the removing and reverting tongs mechanisms occupy while transferring an article from the mold to the point of discharge.

A bottle forming machine, such as that disclosed in the above-1nentioned Lorenz application, includes a plurality of partiblc and invertible blow molds 1 which are carried by a rotating turret and which successively open at a take-out station to release the finished bottles while the bottles are in an inverted or neclcdown position. Only one of these molds, with its cooperating bottom plate 2, is shown in the accompanying drawings.

Referring particularly to Figs. 1 and 2, the present take-out device includes a tongs mechanism A, which is adapted to remove a finished bottle 3 from the mold 1, while in an inverted position, and atongs mechanism B to which the bottle is transferred and which reverts the bottle and delivers it to a conveyor or setting-up buck (l in a rightside up position.

The tongs mecl'ianism A comprises a carrier 4 which mounted at its upper end between arms 5 which are pivotally mounted upon stud shafts 6. These shafts are fixed in a pedestal 8 which is carried by any convenient stationary support, such as the base 0 of the bottle-forming machine. The lower end of the carrier 4 is supported by a lever arm 10, which is pivotally mounted on a shaft ll. This shaft is journaled in bearings l2, which are provided on brackets 13 car d by the pedestal 8.

" coiled spring 18 which surrounds the sleeve between the lower bearing 14 and a collar 19 which is fixed to the sleeve15. The lower end of the sleeve 15 is' provided with a slotted head 20 which limits the upward movement of the st'eadying pin 16 and to which the upper ,end' of a link 21'is pivotally connected.- The lower end of the link 21 is slotted, as indicated at 22, for s iding engagement with a pin 23 on an extension 24 of the lever 10. y

The carrier 4 is also provided, at its upper and lower ends, with pairs of symmetrically arranged bearings 25 and 26, within which a pair of parallel vertical rock shafts 2'? and 28 are respectively mounted. Each of theshafts 27 and 28 carries at its upper end one of a pair of co-acting tongs members 29, which are'provided with complen'ientary bott-l'e-gi'ipping recesses 30 at their outer ends. The shafts 27 and 28 are provided at their lower ends with abutting dogs 31 and 32 (Figs, Band 5), which cause the shafts to rock in unison when actuated to open or close the tongs These tongs are yieldahlyurged towards each other by a spring 33 which surrounds the shaft 28 and which is connected at its lower'end to the lower hearing 26, and at its upper end to a collar 34 which is fixed to the shaft 28. An adjustable stop 35 is provided on the shaft 27 for engagement with a lug 36 formed on the carrier 4, in order to limit the closing movement of the tongs 29.

The carrier. 4 is. urged towards its elevated position by a spring 3'7, acting through connections to be presently described, in order to raise the steadying pin 16 into yielding engagement with the neck 01? the bottle, to clamp the bottle against the bottom plate 2 while the mold is opening, and to also raise the opened tongs 2 9 to a position where they may grasp the bottle after the mold. is opened. This spring 37, as shown in l, is fixed at its lower end to a bracket 38 which is carried by the base 9 or the bottie-forming machinefland is attached at its upper end to ,a flexible connection 39 which passes upwardly and over, and is secured to,

a segment 40 which is fixed to one of the lever arms 5. The upward movement of the carr er 4, and the partsmounted thereon, is

limited by an adjustable stop 41 (Fig. 1)

providedon the pedestal 8 for engagement by a lug 42 on the segment 40.

The upward movement of the carrier 4 under the action of the spring 37 is controlled by a cam 43 which is fixed to a shaft 44. This shaft may be rotated in any suitable manner but preferably driven by'the forming machine and in timed relation therewith. The cam 43 bears against a roller 45 which is carried by arod 46 and which may be adjusted toward and, away from the cam 43 by means of eccentric stud 47, in order to determine the height to which the steaclying pin '16 and thetongs 30 may be raised by a spring 37. One end of the rod 46 is bifurcated, as at 48, for supporting engagement with they shaft 44, and

the other end thereof is pivotally connected to an arm 49 which is fixed to one of the arms 5. p

The rotation of the shaft 44 is so timed that when an inverted'mold 1 comes to rest at the take-out station, the low portion 50 of the cam 43 permits the spring ,37 to ,ele

vate the carrier 4 to the position shown in 1, in which the steading pin 16 vieldably. engages the neck of the bottle and holds the same against the'bottom plate 2 while the mold is opening. Duringthe time that the mold is opening, the roller 45 rides on a dwell 51 of the cam 43, but as soon as the mold has opened suiiicientlyr for the tongs to, enter between the halves thereof, an

extreme low portion 52 of. the cam 43, shown 1n dotted lines in Fig. 1, presents itself to the roller 45 and permits the spring 37 to elevate the carrier 4 still further, against the action of the spring 18. This additional movement of the carrier ra is'es the tongs30 between the opened section of the mold and into alignment with the neck finish of the bottle.

The tongs are held open by a bell crank lever 53, which is mounted on a stud 54 carried by the pedestal 8, One arm 55 of this lever is provided with a plate 56 which is adapted to engage a crank arm 57Iwhich is fixed to the lower cxtreniity of the shaft 27. The other arm58 of the lever is provided with a. roller 59 for engagement with a cam lobe 60 which is carried by a disk 61 fixed to the shaft 44. The plate 56 is of sufiicient length to bear against the crank arm 5'7 and hold the tongs open throughoutthe entire upward travel of the carrier 4.

As soon as the tongs reach the limitof their upward travel, the cam lobe 60 passes from engagement with the roller 59 and permits the plate 56 to recede and the crank arm 57 and the spring 33 to close the tongs into engagement with the ware.

By the time the tongs 30 securely grasp the neck of a bottle, the high portion 62 of the cam 43 bears against the roller 45 and forces the rod 46 to the right (Fig. 1) thereby rocking the lever'arms 49 and 5 in a counter-clockwise direction, as viewed in Fig. 1 of the drawings, against the action of the spring 37. This movement of the parts mentioned lowers the carrier 4 and the elements mounted thereon, and removes the fully blown bottle from the mold.

By reason of the tact that the arms 5 are considerably shorter than the arm 10, the are 01 travel oi the former is considerably greater than that of the latter, and as a re suit, the carrier is tilted to one side as it descends, and this movement serves to remove the bottle from thepath of the mold parts as they invert and to present the bottle to the inverting mechanism B at an inclination to the vertical, as best shown in Fi 8.

The inverting mechanism B comprises a housing 63 provided with trunnions 64 and 65 which are journaled in bearings 66 carried by off-set portions 67 of the brackets 13. Tong arms 68 and 69 are mounted on pivot pins 70 and 71 respectively, which are carried by the housing 63. A pair of co-acting tongs 71 having complementary jaw mem here 72 are adjustably mounted on the forward ends of the arms 68 and 69 by bolt and slot connections 7 3, by means of which the tongs may be adjusted relative to the po sition occupied by the neck of the bottle when presented thereto by the removing mechanism A, in the manner described above.

The tongs are urged towards each other to yieldably grasp the ware by a spring pressed plunger 74 (Fig. 7 which is slidably mounted in the housing 63 and which engages a laterally extending lug 75 provided on the arm 68. This arm is provided with an adjusting screw 76 for engagement with an arm 77 which is also mounted on the pin 70. This arm is provided with a shoulder 78 which engages an arm 79 provided on the arm 69, and forces this arm in aclockwise direction, as viewed in Fig. 7, when the arm 68 is moved in a counter-clockwise direction under the action of the spring pressed plunger 74. The amount that the tongs 71 may be closed is regulated by means of an adjustable stop screw 80. which is threaded into the arm 69 for engagement with the arm 68. The arms 68 and 69 may be swung horizontally in order to accurately position the aws 7 2 of the tongs relative to the neck of a bottle. by adjusting the screw 76. so as to shift the angular position of the arm 77 relative to that of the arm 68.

The tongs 71 are opened to receive and release the ware against the action of the plunger 74 by means of a bell crank lever 81 (Fig. 2), one arm 82 of which bears against a plunger 83 which extends coaxially through the trunnion 65 of the housing 63 and which, in turn, bears against an extension 84 ot' the arm 69 (Fig. 7 The other arm 85 of the bell crank lever 81 is connccted by means of a rod 86 to an arm 87 of the delivery position shown in Fig. 1 by means of a spring l), which is secured at its lower end to the bracket 38, and at its'upper end to a sprocket chain 93. This chain passes upwardly and over a sprocket wheel 94:, which is fixed to the housing 63, and is secured to one arm 95 of abell crank lever 96. The lever 96 is pivotally mounted on a shaft 97 which is journaled in bearings 98 carried by the base of the pedestal 8.. The other arm 99 of the bell crank lever 96 is provided with a roller 100 for engagement with a cam 101 carried by the shaft 14.

A vertically adjustable rest 102 having a shape conforming to that of the side walls of the particular type of bottle being produced, is removably secured to the housing 63 and provides lateral support for the bottle both when the carrier l comes to rest at the end of its lowering and tilting movement, and

also during the reverting operation.

The sequence of operations of the several parts of the device is as follows:

During the time that an inverted mold 1. is approaching the take-out station, the roller 45 is descending the low portion of the cam 43, permitting the carrier 4t to rise under the action oi? the spring 37. As soon. the mold comes to rest, the steadying pin 16 engages the neck of the bottle (Fig. 9) and clamps the bottle against the bottom plate 2 while the mold is opening. During this time the roller 4-5 is riding upon the dwell 51 ot the cam 1-3, but as soon the mold is opened, the extreme low portion 52 ot' the cam 43 presents itselt to the roller 4:5 and permits the spring 37 to elevate the carrier still iturther. This additional movement of the carrier raises the tongs 30 between the open sections of the moldv and into alignment with the finish 0'! the bottle. and inasmuch as the movement of the steadying pin 16 is arrested through contact with the bottle, this additional elevation of the carrier compresses the spring 18.

During the upward travel of the carrier 4, the cam lobe 60 acts on the roller 59 to maintain the plate 56 in engagement with the crank arm 57 and the tongs are thus held open against the action of the spring 33, but as soon as the carrier 4 reaches the limit of its upward travel, the cam lobe 60 moves from engagement with the roller 59.

ili'i u This permits the plate 56 to release the crank 57, and the spring 33 to close the tongs into gripping contact with the neck oi the bottle (Fig. 10).

The high portion 62 oi the cam 43 now engages the roller andforces the rod to the right, as viewed in Fig. 1, which lowers and tilts the carrier 4t and the tongs 30, and thusremoves the bottle from the mold. The downward travel of the carrier 4 moves the pin 23 on the extension 52-1- of the arm 10 into abutting engagement with the lower end of the slot 22 and withdraws the steadying pin from engagement with the neckolf the bottle, leaving the bottle entirely snp- Ported by the tongs 3o At the'bceinning of the descent of the re moving mechanism, the cam 101 engages the roller .100 and forces the arms 99 and of the bell-crank lever 08 in a clockwise cirection (F 1). This movei'nent of the lever 98 causes the chain 93 to impart a rotary movement in a.countar-clockwise direction to the sprocket wheel 94- against the mechanism A reaches its lowermost position.

As the removing,mechanism A completes its downward travel, it carries the neck of the bottle between the opened jaws 72 of the tongs ,71 and the body of the bottle into supporting engagement with the rest 1102 (Figs. 8 and 12). In this position the loottlc is outside of the path oi the mold 1., which may invert, close, and pass on to its next station, and sru'iicient clearance is provided for the next succeeding mold to advmedium of the bell crank lever 88, rod. 80,

bell crank lever 81 and 'ilungor 83. As soon, however, as the neck oi the bottle has been positioned between the jaws T2 of the tongs 71, as above described the cam lobe pas. from engagement with the rollerllt), thus rcleasing the lever .88 and permitting the tongs T1 to be closed under the actionoii the spring pressed plunger Z l. The cam lobe next releases the lever {38, permitting the tongs 30 to open and release the bottle under the action-oi? the spring A this stage in. the operation oi? the machine, the low portion of the cam 101 presents itself to the roller 100, and permits the spring .92 to rock the sprocket wheel 94 in a clockwise direction. This movement of the sprocket wheel 94 swings the tongs 71 upwardly and over to the positionyshown in the-full lines in Fig. 1', and transfers the bottlelrom the removing mechanism A to.

to the axis of swing of the removing mech,

anism. This particular construction is made necessary by reason of the fact that in molds designed for ware of rectangular cross section, the line of CllVlSlOIl between the sections of the mold occurs along the opposite vertical edges of the ware and as a result, it the ware is transferred to the buck or conveyor in a plane disposed at, right angles to the conveyonit will be deposited thereon with its flat sides disposed at an angle to the path of movement of the conveyor, as shown by dotted lines at a in Fig. 2. Such an arrangement of ware on a conveyor is undesirable for several reasons,

chief among wiich is that difficulty is encountered in shoving the bottles oil from the buck to the lehr conveyor, more space is occupied by the ware on the buck and in the lehr, and the ware is subjected to varying thermal conditions in the lehr occasioned by the proximity of the adjacent edges of theware and the remoteness of the list sides thereof.

By means of the present construction the inverting mechanism B imparts a one-eighth turn to the ware during its inversion and deposits it on the conveyor 0 with the fiat sides of the Ware disposed parallel to the path of movement thereof.

While we have shown and described a take-out mechanism designed especially for handling bottles of rectangular crosssection delivered by a shaping machine such as that disclosed in the above-mentioned Lorenz application, it will be understood that this mechanism may also be employed. for l1andling were of other shapes, and that the angularityand posi ion oi? the axis of swing of the inverting mechanism may be changed so as to deposit the ware on the conveyor in any desired position in accordance with the initial angular positioniot' the ware in the mold and the relative angular position of the conveyor. In this and other respects the present take-out device may be modified within the scope of the appended claims.
